Container

ABSTRACT

A container for a plurality of articles comprising a main body, a hollow member fixedly coupled to an end of the main body and a cup member movably coupled to the hollow member. When the cup member is in an open position the cup member and the hollow member are spaced defining an opening. A slider is movably coupled to the cup member. The slider has a spring, such that when the slider is moved relative to the cup member in a radial direction the slider carries an article towards the opening and the spring on the slider is flexed. After dispensing, the spring gradually relaxes, resetting the slider.

FIELD OF THE INVENTION

The present invention is generally directed to a container, and more particularly to a container for a plurality of dissolvable articles.

BACKGROUND OF THE INVENTION

Some personal care products, including shampoos, conditioners, body washes, facial cleansers, and hand soaps, are available in a solid unit dose form. Such products may include dissolvable films, compressed powders in a solid, fibrous structures, porous foams, soluble deformable solids, powders, bars, or prills. Ideally, these products can be formulated to dissolve almost instantly when exposed to liquid water. However, this creates problems with storing the products, as it is generally most convenient to store personal care products where they will be used (e.g., in the shower, bathtub, or adjacent to a sink), and protecting the products through the supply chain and expected shelf life. However, these convenient storage locations are generally very humid and/or the products/articles can accidentally be splashed with water prior to use, causing the products to dissolve into a liquid personal care product and/or a gummy mess.

Currently, dissolvable unit dose products can be packaged individually. However, this is inconvenient because consumers must unwrap each article prior to use and dispose of the packaging, and the consumers generally do not have trash or recycling receptacles in the shower. Alternatively, the consumers can store the products away from the shower, bathtub, or sink and then they have to remember to take an article with them to a usage location every time they want to wash.

Therefore, there is a need for a container that can hold multiple doses of dissolvable unit dose consumer products, can allow for convenient, intuitive dispensing of the consumer products, and enables consumers to store the container in a humid environment where they will use the product, such as a shower, bathtub, or sink.

DETAILED DESCRIPTION OF THE INVENTION

While the specification concludes with claims particularly pointing out and distinctly claiming the invention, it is believed that the present disclosure will be better understood from the following description.

It should be understood that every maximum numerical limitation given throughout this specification includes every lower numerical limitation, as if such lower numerical limitations were expressly written herein. Every minimum numerical limitation given throughout this specification will include every higher numerical limitation, as if such higher numerical limitations were expressly written herein. Every numerical range given throughout this specification will include every narrower numerical range that falls within such broader numerical range, as if such narrower numerical ranges were all expressly written herein.

The invention relates to a container for a plurality of arranged articles. The articles can be arranged in an orderly, semi-orderly/seemingly random, or random arrangement. In some examples, the articles can be stacked on top of each other. In other examples, the articles can be arranged side-by-side. The plurality of articles may be, for example, personal care and other consumer products in a solid form, including shampoos, conditioners, body washes, hand soaps, and facial cleansers. The plurality of articles can also be consumer products including laundry detergent, fabric softeners, fabric conditioners, household cleaners, dish soap, dishwasher detergent, toothpaste, mouthwash, etc. The container may store and dispense the plurality of articles, in some examples the articles can be directly stacked on top of one another and/or arranged side-by-side without material intervening.

The container comprises a main body having a hollow tubular shape and extending along a longitudinal axis. In some examples, the main body can be any hollow shape. For example, it can have a cross section that can be any shape including polygons, polygons with rounded corners, circular which includes oval, irregular shapes, etc. The main body comprises a first end and a second end opposing the first end. At least the second end may be open. The container further comprises a hollow member fixedly coupled to the main body at the second end and defining a first opening therethrough extending angularly about the longitudinal axis. The container further comprises a cup member rotatably coupled to the hollow member, such that the cup member may be rotatable relative to the hollow member about the longitudinal axis. The cup member defines a second opening therethrough extending angularly about the longitudinal axis. The cup member comprises a base portion defining a closed bottom end of the container and defining a grooved track facing the second end of the main body. The container further comprises a cam arm received within the hollow member and the cup member. The cam arm may be movably coupled to the hollow member and comprises a protrusion movably engaged with the grooved track, such that the cam arm moves relative to the hollow member due to a relative rotation between the hollow member and the cup member. The main body, the hollow member, and the cup member together receive the plurality of articles therein. The hollow member and the cup member are rotatable relative to each other between an open configuration and a closed configuration. In the open configuration, the first and second openings are at least partially aligned with each other to form a dispensing opening. In the closed configuration, the first and second openings are misaligned from each other to close the dispensing opening. The cam arm moves between an engaged position corresponding to the closed configuration and a dispensing position corresponding to the open configuration due to the relative rotation between the hollow member and the cup member. In the engaged position, the cam arm may be configured to engage a bottom article from the plurality of articles. The cam arm may be further configured to move the bottom article due to the relative rotation between the hollow member and the cup member, such that, in the dispensing position of the cam arm, the bottom article at least partially extends through the dispensing opening and may be removable from the container.

The container may reduce or prevent contact between the plurality of articles stored within the container and moisture present in an external environment (e.g., a shower, near a sink, or a humid bathroom) where the container may be disposed. Therefore, the container may reduce or prevent external moisture from being absorbed by the plurality of articles stored within the container. Further, the container may enable consumers to store or situate the container storing the plurality of articles in a humid environment where they will use the plurality of articles, such as a shower, bathtub, or sink.

In some cases, the main body may be substantially free of plastics, and can be made of paper, carton board, and/or a metal foil (e.g., aluminum or steel). Further, the hollow member, the cup member, and the cam arm may be made of plastic. Relative dimensions and weights of the main body, the hollow member, the cup member, and the cam arm may be selected such that the main body forms the bulk of the container, and an overall plastic content of the container may be low as compared to conventional containers that are fully made of plastic. The main body may be at least partially covered by a wrap-label and/or a coating to protect the main body from moisture during use (e.g., from splashes, wet hands, etc.).

In some cases, a support member may be disposed below the base portion of the cup member to separate the base portion from moisture (e.g., standing water) in an event of the container being placed on a moist surface.

The container may further provide an easy to use, intuitive dispensing mechanism to dispense the bottom article from the container. Specifically, a relative rotation between the hollow member and the cup member from the closed configuration to the open configuration in a first direction about the longitudinal axis may cause the cam arm to move from the engaged position to the dispensing position. After removal of the bottom article from the container, a relative rotation between the hollow member and the cup member from the open configuration to the closed configuration in a second direction opposite to the first direction may cause the cam arm to move from the dispensing position to the engaged position and engage a successive bottom article from the plurality of articles. Therefore, the plurality of articles may be easily and conveniently dispensed from the container. In some examples, the container can be stored horizontally. In other examples, the top article can be dispensed.

Thus, the opening of the container and the dispensing of the bottom article may be achieved in a single action by a consumer. Specifically, the relative rotation between the hollow member and the cup member from the closed configuration to the open configuration may simultaneously expose the dispensing opening and dispense the bottom article at least partially through the dispensing opening. Further, closing of the container and priming the container for future dispensing of the successive bottom article may also be achieved in another single action by the consumer. Specifically, the relative rotation between the hollow member and the cup member from the open configuration to the closed configuration may close the dispensing opening and cause the cam arm to engage the successive bottom article for future dispensing.

The container may further comprise a cap coupled to the main body at the first end. The cap may be configured to close the first end of the main body to define a closed top end of the container. The cap may inhibit pooling of water on the closed top end of the container. In some cases, the cap may be made of paper and/or aluminum. In such cases, a rigid or flexible plastic covering may be at least partially disposed on the cap to protect the cap from moisture (e.g., from splashes and water from a shower head that may be located near the container).

The container may further comprise a follower slidably received within the main body and configured to engage the plurality of articles, such that the plurality of articles may be received at least partially between the follower and the cam arm relative to the longitudinal axis. The follower may reduce or prevent misalignment of the plurality of articles in case the container is tipped over. The follower may also provide a moisture sink inside the container. The moisture sink can include an absorbent material (e.g. absorbent gelling material), desiccant, etc.

The hollow member may further comprise a first coupling portion fixedly coupled to the main body and a second coupling portion rotatably coupled to the cup member. The second coupling portion may define the first opening as an angular cut-out. The hollow member may further comprise a projection disposed between the first and second coupling portions. The projection may engage with each of the main body and the cup member, such that the projection is disposed between the main body and the cup member along the longitudinal axis. Specifically, the projection may engage with corresponding axial ends of the main body and the cup member, such that the cup member does not directly contact or engage the main body. This may enable the cup member to freely rotate relative to the main body. The cup member may include ridges or other textures that may be made from the primary material of the cup member or may be an added material such as a low-durometer material that facilitate gripping and turning it.

The hollow member may further comprise a plurality of shaped portions disposed on an outer surface of the first coupling portion. The shaped portions may engage the main body to rotationally and/or axially fix the main body and the hollow member relative to each other. In some examples, the member may be permanently joined to the body such as through adhesive, crimping, and/or riveting. In other examples, the member may be temporarily joined to the body.

The hollow member may further comprise an angular projection disposed at an end of the hollow member. The cup member may further define an angular slot movably engaging with the angular projection of the hollow member to allow the relative rotation between the hollow member and the cup member.

The cup member may further comprise a portion, which can be an annular portion, defining the second opening as an angular cut-out, and a connecting portion connecting a circumferential edge of the base portion with the portion. The angular slot may be defined between the circumferential edge of the base portion, the annular portion, and the connecting portion.

The cup member may further comprise a lip disposed at an end distal to the base portion. The hollow member may further comprise a groove at least partially receiving the lip of the cup member therein, such that the lip is rotatable relative to the groove.

The hollow member may further comprise a coupling feature extending from an inner surface of the hollow member. The cam arm may further comprise a coupling element received at least partially through the coupling feature to pivotally couple the cam arm to the coupling feature.

The coupling feature may comprise a narrow aperture, a shoulder disposed adjacent to the narrow aperture, and a wide aperture disposed adjacent to the shoulder and opposite to the narrow aperture. The coupling element of the cam arm may comprise a narrow portion pivotally received at least partially within the narrow aperture and a wide portion pivotally received at least partially within the wide aperture and engaging with the shoulder. The engagement between the wide portion of the coupling element and the shoulder of the coupling feature may secure the coupling element to the coupling feature.

The cam arm may further comprise a receiving portion configured to receive the bottom article thereon and an engaging portion extending from and inclined to the receiving portion. The engaging portion may be configured to engage with and move the bottom article towards the dispensing opening. The protrusion may extend from the receiving portion. Specifically, the protrusion and the engaging portion may extend from opposing major surfaces of the receiving portion. Further, the engaging portion may enable the bottom article to be reliably moved towards the dispensing opening when the cam arm moves from the engaged position to the dispensing position. Specifically, the engaging portion may prevent substantial slippage between the bottom article and the cam arm. The engaging portion may therefore prevent the bottom article from remaining stationary within the container while the cam arm moves to the dispensing position.

The cam arm may further comprise a curved portion extending from the engaging portion and distal to the receiving portion. In the engaged position, the curved portion may engage an inner surface of the hollow member.

The receiving portion of the cam arm may further define a V-shaped notch spaced apart from the engaging portion. In some cases, the V-shaped notch may act as a rotational stop for the cam arm by selectively engaging with the coupling element. The V-shaped notch may allow the cam arm to freely rotate about the coupling feature without interference. Moreover, the V-shaped notch may further reduce plastic content of the container (in cases where the cam arm is made of plastic).

The grooved track may extend from a first groove end to a second groove end. In the engaged position, the protrusion of the cam arm may engage with the first groove end of the grooved track. In the dispensing position, the protrusion of the cam arm may engage with the second groove end of the grooved track. The engagement between the protrusion and the first groove end may act as a first stop corresponding to the engaged position. Similarly, the engagement between the protrusion and the second groove end may act as a second stop corresponding to the dispensing position.

The base portion may comprise a first major surface and a second major surface opposite to the first major surface. The grooved track may extend from the first major surface. The cam arm may be at least partially disposed on the first major surface and move along the first major surface between the engaged position and the dispensing position. In some cases, the cam arm may substantially move along a plane of the first major surface of the base portion.

The base portion may further comprise a continuous side wall extending from the first major surface beyond the second major surface and a bottom wall connected to the continuous side wall and distal to the first major surface. The continuous side wall and the bottom wall may define the grooved track therebetween. The continuous side wall may have a suitable height to facilitate reliable engagement between the protrusion and the grooved track.

The base portion may further comprise a plurality of interconnected ribs extending from the second major surface and a rib extending from the second major surface and surrounding the plurality of interconnected ribs. The rib may be connected to at least some of the plurality of interconnected ribs. At least some of the plurality of interconnected ribs may define a plurality of hexagonal shapes. At least some of the plurality of interconnected ribs may be connected to the continuous side wall. The rib and the interconnected ribs may provide additional rigidity to the cup member. Further, the rib and the interconnected ribs may minimize contact between the base portion and moisture (e.g., standing water) that may be present on an external surface on which the container is placed. In some cases, an additional support member may be disposed on the rib to further minimize contact between the base portion and moisture present on the external surface.

FIGS. 1A and 1B respectively show a front perspective view and a schematic sectional view of a container 100 for a plurality of arranged articles 10 stacked on top of each other according to a first aspect of the invention. Further, FIG. 2 shows an exploded perspective view of the container 100.

The plurality of articles 10 may be consumer products in a solid form. Specifically, the plurality of articles 10 may be personal care articles in the solid form, including, but not limited to, shampoos, conditioners, body washes, facial cleanser, and hand soap. For example, the plurality of articles 10 may be fibrous structures or porous foam structures that become liquid shampoo, liquid conditioner, liquid body wash, liquid face wash, and/or a liquid hand wash upon hydration, as described in US Pub. Nos. 2018/0333339, 2019/0282461, and 2020/0405587, incorporated by reference herein. In some cases, the plurality of articles 10 may be unit dose solid products. The plurality of articles 10 may have any suitable shape, such as circular, triangular, rectangular, polygonal, hexagonal, and the like, as per application requirements. The plurality of articles can be shaped similarly to the cross-section of the dispenser. The plurality of articles 10 stacked on top of each other comprise a bottom article 10A. The bottom article 10A may be a lowermost article of the plurality of articles 10.

Referring to FIGS. 1A, 1B, and 2 , the container 100 comprises a main body 110. The main body 110 has a hollow shape. In some examples, the hollow shape can be tubular and/or can have an annular cross-section. In other examples the hollow shape can have a cross-section that is circular which includes oval, rectangular which includes square, hexagonal, another polygon, a convex shape, a concave shape, a teardrop shape, a flower shape, a star shape, or any other suitable shape. The hollow tubular shape may allow the main body 110 to accommodate some of the plurality of articles 10 therein. As shown in FIGS. 1A, 1B, and 2 , the main body 110 may have a hollow circular cylindrical shape.

The main body 110 comprises a first end 112 and a second end 114 opposing the first end 112. In other words, the second end 114 is opposite to the first end 112. The main body 110 extends along a longitudinal axis 111. Specifically, the main body 110 may extend along the longitudinal axis 111 between the first end 112 and the second end 114. At least the second end 114 is open. In other words, the main body 110 is open at the second end 114 thereof.

The first end 112 may be closed. For example, as shown in FIG. 1 , the container 100 may further comprise a cap 180 coupled to the main body 110 at the first end 112. The cap 180 may be configured to close the first end 112 of the main body 110 to define a closed top end 102 of the container 100. The cap 180 may prevent accumulation of water on the closed top end 102 of the container 100, for example, by having a curved concave shape. In other words, the cap 180 may inhibit pooling of water on the closed top end 102 of the container 100. Alternatively, in some examples, the main body 110 may comprise a top portion integral with the main body 110 to close the first end 112, and to define the closed top end 102 of the container 100. In other words, the main body 110 may be pre-closed. For example, the main body 110 may be similar to a cup or a can (e.g., an aluminum can) with the top portion closing the first end 112 and defining the closed top end 102 of the container 100. The top portion may be configured to prevent accumulation of water on the closed top end 102 of the container 100, similar to the cap 180 described above.

The container 100 further comprises a hollow member 120 (shown more clearly in FIG. 2 ). The hollow member 120 can be at least partially received in the main body 110. In other words, at least a portion of the hollow member 120 may be received within the main body 110. The hollow member 120 may be fixedly coupled to the main body 110 at the second end 114. The hollow member 120 may not be movable relative to the main body 110. Specifically, the hollow member 120 may not move linearly and/or rotationally relative to the main body 110. Therefore, the hollow member 120 may rotate with the main body 110. The hollow member 120 defines a first opening 121 (shown in FIG. 2 ) therethrough extending angularly about the longitudinal axis 111.

The container 100 further comprises a cup member 140 rotatably coupled to the hollow member 120, such that the cup member 140 may be rotatable relative to the hollow member 120 about the longitudinal axis 111. The cup member 140 defines a second opening 141 (shown in FIG. 2 ) therethrough extending angularly about the longitudinal axis 111.

The second opening 141 of the cup member 140 may be substantially similar to the first opening 121 of the hollow member 120 in shape and dimensions, such that the second opening 141 and the first opening 121 may define a dispensing opening 106 upon at least partial alignment thereof. In other words, the cup member 140 and/or the hollow member 120 may be rotated relative to each other about the longitudinal axis 111, such that the first and second openings 121, 141 may at least partially align with each other and define the dispensing opening 106. The dispensing opening 106 defined by the first and second openings 121, 141 may have suitable shape and dimensions to allow at least one article (e.g., the bottom article 10A) from the plurality of the articles 10 to be dispensed therethrough.

The cup member 140 comprises a base portion 142. The base portion 142 defines a closed bottom end 104 of the container 100. The closed bottom end 104 may be opposite to the closed top end 102 of the container 100. The base portion 142 further defines a grooved track 145 facing the second end 114 of the main body 110.

The container 100 further comprises a cam arm 160 received within the hollow member 120 and the cup member 140. The cam arm 160 may be movably coupled to the hollow member 120. For example, the cam arm 160 may be pivotally coupled to the hollow member 120. The cam arm 160 comprises a protrusion 162 (shown in FIG. 2 ) movably engaged with the grooved track 145, such that the cam arm 160 moves relative to the hollow member 120 due to a relative rotation between the hollow member 120 and the cup member 140. Specifically, the protrusion 162 movably engaged with the grooved track 145 causes the cam arm 160 to move relative to the hollow member 120 due to the relative rotation between the hollow member 120 and the cup member 140. In other words, the protrusion 162 may be configured travel along the grooved track 145 and cause a movement of the cam arm 160 with respect to the hollow member 120 due to the relative rotation between the hollow member 120 and the cup member 140.

The relative rotation between the hollow member 120 and the cup member 140 can be achieved in any suitable manner. For example, the relative rotation between the hollow member 120 and the cup member 140 can be achieved by rotating the main body 110 (since the hollow member 120 may be fixedly coupled to the main body 110) with respect to the cup member 140, by rotating the cup member 140 with respect to the main body 110, or by rotating the main body 110 and the cup member 140 opposite to each other.

As shown in FIG. 1B, the main body 110, the hollow member 120, and the cup member 140 together receive the plurality of articles 10 therein. As discussed above, some of the plurality of articles 10 may be accommodated in the main body 110. Further, at least one of the plurality of articles 10 may be received within the hollow member 120 and the cup member 140. As discussed above, the plurality of articles 10 can include the bottom article 10A. The container 100 may be configured to dispense at least the bottom article 10A through the dispensing opening 106 (shown in FIG. 1 ). In some cases, the container 100 may be configured to sequentially dispense successive bottom articles from the stack of the plurality of articles 10 through the dispensing opening 106.

The container 100 may further comprise a follower 185. The follower 185 may be slidably received within the main body 110. Specifically, the follower 185 may slidably engage an inner surface of the main body 110. The follower 185 may be configured to engage the plurality of articles 10, such that the plurality of articles 10 may be received at least partially between the follower 185 and cam arm 160 relative to the longitudinal axis 111. The follower 185 may have a section that slidably engages with the main body 110 and a base section disposed at an end of the section. The base section of the follower 185 may engage a top article 10B from the plurality of articles 10. The top article 10B may be an uppermost article of the plurality of articles 10 stacked on top of each other. The follower 185 may be configured to slide along the longitudinal axis 111 to maintain engagement with the plurality of articles 10. Advantageously, the follower 185 may reduce or prevent misalignment of the plurality of articles 10 in case the container 100 is tipped over. In other words, the follower 185 may maintain the plurality of articles 10 in an aligned stack in case the container 100 is tipped over.

The main body 110 may be configured to provide compression resistance and moisture barrier to the container 100. In other words, the main body 110 may protect the plurality of articles 10 from compression (e.g., by external forces incurred by the container 100 during shipping or usage thereof) and may reduce or prevent contact between the plurality of articles 10 stored within the container 100 and moisture present in an external environment (e.g., a shower) where the container 100 is disposed. Therefore, the container 100 may reduce or prevent external moisture from being absorbed by the plurality of articles 10 stored within the container 100.

The main body 110 may be primarily made of a paper material and may be substantially free of plastic. Specifically, the main body 110 may comprise from 0% to 5% by weight of plastic. The main body 110 made of the paper material may comprise barrier materials to protect the main body 110, for example, against moisture, grease/oils, oxygen, etc. The barrier materials may be coatings (applied before or after paper forming) or additional construction layers, such as films or aluminum foil. One example of the barrier materials is VaporCoat® 2200R, commercially available from Michelman® Incorporated, Cincinnati, Ohio. However, the barrier materials may comprise any other printed, sprayed, or laminated barrier materials.

In some examples, the paper material of the main body 110 may be spiral wound. That is, the paper material may comprise an interior layer, an outer layer, and one or more inner layers disposed between the interior and outer layers. Further, each of the interior layer, the one or more inner layers, and the outer layer may be wrapped around a mandrel. Each of the inner layer, the outer layer, and the one or more internal layers may be coated with the barrier materials. In one example, the inner layer may be coated with a layer of aluminum foil. Further, in one example, the outer layer may be coated with VaporCoat® 2200R. Alternatively, the main body 110 may be constructed from a carton board that may be formed into a generally cylindrical shape and comprise the barrier materials for protection thereof.

The cap 180 may be made of a plastic, for example, by injection molding. Alternatively, the cap 180 may be made of a formed pulp with the barrier materials applied to the formed pulp. Alternatively, the cap 180 can be made of metal (e.g., aluminum).

The follower 185 may be primarily made of a paper material. Additionally, the follower 185 may provide a moisture sink inside the container 100. In other words, the follower 185 may absorb moisture that may enter into the container 100 from the external environment.

Each of the hollow member 120, the cup member 140, and the cam arm 160 may be made of a plastic. Alternatively, each of the hollow member 120, the cup member 140, and the cam arm 160 may be made of injection molded pulp, or a combination of injection molded paper and plastic. In some examples, each of the hollow member 120, the cup member 140, and the cam arm 160 may be made of aluminum.

Further, the container 100 may be substantially made of paper and/or aluminum. In some examples, the container 100 may comprise less plastic per dose than current liquid shampoo bottles. In some examples, the container 100 can contain less than 60% plastic, less than 55% plastic, or less than 50% plastic.

FIGS. 3A and 3B respectively show a side perspective view and a bottom perspective view of the hollow member 120. The hollow member 120 may comprise a first coupling portion 122 and a second coupling portion 124. The hollow member 120 may further comprise a projection 123 disposed between the first and second coupling portions 122, 124.

Referring to FIGS. 2, 3A, and 3B, the first coupling portion 122 may be fixedly coupled to the main body 110. Specifically, the first coupling portion 122 may be fixedly coupled to the main body 110 at the second end 114 thereof. The first coupling portion 122 may be at least partially received in the main body 110 at the second end 114 to fixedly couple the hollow member 120 to the main body 110. In some cases, the first coupling portion 122 may be configured to form an interference fit with the main body 110 at the second end 114.

As shown in FIGS. 3A and 3B, the hollow member 120 may further comprise a plurality of shaped portions 125 disposed on an outer surface 126 of the first coupling portion 122. In other words, the first coupling portion 122 may comprise the plurality of shaped portions 125. In some examples, the plurality of shaped portions 125 may be tapered. Further, the shaped portions 125 may taper from the projection 123. The plurality of shaped portions 125 may facilitate in formation of the interference fit between the first coupling portion 122 and the main body 110 to fixedly couple the hollow member 120 to the main body 110. Specifically, the shaped portions 125 may engage the main body 110 to rotationally and/or axially fix the main body 110 and the hollow member 120 relative to each other.

The second coupling portion 124 may define the first opening 121 (also shown in FIG. 2 ) as an angular cut-out. Further, the second coupling portion 124 may be rotatably coupled to the cup member 140. In other words, the cup member 140 may be rotatable about the second coupling portion 124. Specifically, the hollow member 120 may further comprise a groove 130. The groove 130 may be disposed on the second coupling portion 124 and adjacent to the projection 123. The groove 130 may be configured to at least partially receive a portion of the cup member 140 therein, such that the cup member 140 may be rotatable relative to the hollow member 120.

The hollow member 120 may further comprise an angular projection 127 disposed at an end 128 of the hollow member 120. The end 128 may be distal to the first coupling portion 122.

The coupling feature 132 may comprise a narrow aperture 134, a shoulder 135 disposed adjacent to the narrow aperture 134, and a wide aperture 136 disposed adjacent to the shoulder 135 and opposite to the narrow aperture 134. The narrow aperture 134 may have a narrow width 134W, and the wide aperture 136 may have a wide width 136W. In some examples, the wide width 136W may be from about 1.1 times to about 3 times greater than the narrow width 134W. In some examples, the wide width 136W may be about 2 times greater than the narrow width 134W. The narrow aperture 134, the shoulder 135, and the wide aperture 136 may be configured to receive a portion of the cam arm 160 to pivotally couple the cam arm 160 to the coupling feature 132.

The base portion 142 may further comprise a first major surface 144 and a second major surface 146 opposite to the first major surface 144. The grooved track 145 may extend from the first major surface 144. Further, the grooved track 145 may extend from a first groove end 145A to a second groove end 145B.

Referring to FIGS. 3A to 4B, the cup member 140 may comprise a lip 143 disposed at an end 156 distal to the base portion 142. The groove 130 (shown in FIGS. 3A and 3B) may at least partially receive the lip 143 of the cup member 140 therein, such that the lip 143 may be rotatable relative to the groove 130. As a result, the cup member 140 may be rotatable about the hollow member 120.

The base portion 142 may further comprise a continuous side wall 147 and a bottom wall 148. The continuous side wall 147 may extend from the first major surface 144 beyond the second major surface 146. The bottom wall 148 may be connected to the continuous side wall 147 and may be distal to the first major surface 144. The continuous side wall 147 and the bottom wall 148 may define the grooved track 145 therebetween. The continuous side wall 147 may have a continuous curved shape and may define the first and second groove ends 145A, 145B of the grooved track 145.

As shown in FIG. 4B, the base portion 142 may further comprise a rib 149 extending from the second major surface 146. The base portion 142 may further comprise a plurality of interconnected ribs 150 extending from the second major surface 146. The rib 149 may surround the plurality of interconnected ribs 150. The rib 149 may be connected to at least some of the plurality of interconnected ribs 150. At least some of the plurality of interconnected ribs 150 may be connected to the continuous side wall 147. Further, at least some of the plurality of interconnected ribs 150 may define a plurality of hexagonal shapes 153. Alternatively, at least some of the plurality of interconnected ribs 150 may define a plurality of other shapes, including, but not limited to, circular shapes, triangular shapes, rectangular shapes, and any suitable polygonal shapes.

Moreover, as shown in FIG. 4B, the cup member 140 may further comprise a portion 152, which can be an annular portion, and a connecting portion 154. The portion 152 may define the second opening 141 as an angular cut-out. Further, the connecting portion 154 may connect the circumferential edge 142E of the base portion 142 with the portion 152.

The cup member 140 may further define an angular slot 151 movably engaging with the angular projection 127 (shown in FIGS. 3A and 3B) of the hollow member 120 to allow the relative rotation between the hollow member 120 and the cup member 140. In some examples, the angular slot 151 may be defined between the circumferential edge 142E of the base portion 142, the portion 152, and the connecting portion 154.

FIGS. 5A and 5B respectively show a top perspective view and a bottom perspective view of the cam arm 160. FIG. 5C shows a cross-sectional view of the cam arm 160 taken along a line 2-2 of FIG. 5A.

Referring to FIGS. 1A, 1B, and 3A to 5C, the cam arm 160 may comprise a receiving portion 163 and an engaging portion 164. The receiving portion 163 may comprise a first major surface 165 and a second major surface 166 opposite to the first major surface 165. The receiving portion 163 may be configured to receive the bottom article 10A (shown in FIG. 1B) thereon. Specifically, as shown in FIG. 5A, the receiving portion 163 may be configured to receive the bottom article 10A on the first major surface 165 thereof. The receiving portion 163 of the cam arm 160 may further define a V-shaped notch 167 spaced apart from the engaging portion 164. In some cases, the V-shaped notch 167 may act as a rotational stop for the cam arm 160. The V-shaped notch 167 may allow the cam arm 160 to freely rotate about the coupling feature 132 (shown in FIG. 3B) without interference. Moreover, the V-shaped notch 167 may further reduce plastic content of the container 100 (in cases where the cam arm 160 is made of plastic).

As discussed above, the cam arm 160 comprises the protrusion 162. The protrusion 162 may extend from the receiving portion 163. Specifically, the protrusion 162 may extend from the second major surface 166 of the receiving portion 163. The protrusion 162 may be designed (e.g., the protrusion 162 may have a suitable width), such that the protrusion 162 may engage the continuous side wall 147 (shown in FIG. 4A) of the grooved track 145 to force it to travel along the grooved track 145 upon the relative rotation between the hollow member 120 and the cup member 140. As shown in FIG. 5B, the protrusion 162 may have a substantially circular cylindrical shape. However, the protrusion 162 may have any suitable shape and dimensions based on cross-sectional shape and dimensions of the grooved track 145.

The engaging portion 164 may extend from the receiving portion 163. Specifically, the engaging portion 164 may extend from the first major surface 165 of the receiving portion 163. Further, the engaging portion 164 may be inclined to the receiving portion 163. As shown in FIG. 5C, the engaging portion 164 may define an angle θ with respect to the first major surface 165 of the receiving portion 163. In some examples, the angle θ may be from about 60 degrees to about 120 degrees. In some examples, the engaging portion 164 may be substantially perpendicular to the receiving portion 163, i.e., the angle θ may be about 90 degrees.

The engaging portion 164 may be configured to engage with and move the bottom article 10A (shown in FIG. 1B) towards the dispensing opening 106 (shown in FIG. 1A). For example, the engaging portion 164 may be configured to only move the bottom article 10A towards the dispensing opening 106. While the engaging portion 164 moves the bottom article 10A, a subsequent article 10 from the plurality of articles 10 disposed above the bottom article 10A may contact a top of the engaging portion 164. In some use cases, the engaging portion 164 may be configured to move two, three, four, or five of the plurality of articles 10 towards the dispensing opening 106.

Referring to FIGS. 3A to 5C, the cam arm 160 may further comprise a curved portion 168 extending from the engaging portion 164 and distal to the receiving portion 163. The curved portion 168 may engage the inner surface 129 (shown in FIG. 3B) of the hollow member 120.

The cam arm 160 may further comprise a coupling element 170. The coupling element 170 may be received at least partially through the coupling feature 132 (shown in FIG. 3B) to pivotally couple the cam arm 160 to the coupling feature 132. In other words, the cam arm 160 can pivot about the coupling feature 132 when the coupling element 170 is received at least partially through the coupling feature 132. As shown in FIGS. 5A and 5B, the coupling element 170 of the cam arm 160 may comprise a narrow portion 172 and a wide portion 174. The coupling element 170 will be further described below with reference to FIG. 6 .

FIG. 6 shows a cross-sectional perspective view of a portion of the container 100 taken along a line 1-1 of FIG. 1 .

As discussed above, the coupling element 170 may be received at least partially through the coupling feature 132 of the hollow member 120 to pivotally couple the cam arm 160 to the coupling feature 132. Specifically, as shown in FIG. 6 , the narrow portion 172 may be pivotally received at least partially within the narrow aperture 134. The wide portion 174 may be pivotally received at least partially within the wide aperture 136. Further, the wide portion 174 may engage with the shoulder 135. In other words, the cam arm 160 may be pivotally coupled to the coupling feature 132 via pivotal coupling of the narrow portion 172 to the narrow aperture 134, and the wide portion 174 to the wide aperture 136. Further, the cam arm 160 may be at least partially disposed on the first major surface 144 and may move along the first major surface 144. The engagement of the wide portion 174 of the coupling element 170 with the shoulder 135 of the coupling feature 132 may ensure that the cam arm 160 is disposed on and moves along the first major surface 144 of the base portion 142.

Further, the projection 123 may engage with each of the main body 110 and the cup member 140, such that the projection 123 may be disposed between the main body 110 and the cup member 140 along the longitudinal axis 111.

The first coupling portion 122 may be fixedly coupled to the main body 110. Specifically, the shaped portions 125 may engage the main body 110 to rotationally and/or axially fix the main body 110 and the hollow member 120 relative to each other.

The second coupling portion 124 may be rotatably coupled to the cup member 140. Specifically, the groove 130 may at least partially receive the lip 143 of the cup member 140 therein, such that the lip 143 may be rotatable relative to the groove 130. The lip 143 of the cup member 140 may engage the groove 130 of the hollow member 120, such that the cup member 140 may be rotatable relative to the hollow member 120. Furthermore, the angular slot 151 may movably engage with the angular projection 127 of the hollow member 120 to allow the relative rotation between the hollow member 120 and the cup member 140.

FIGS. 7A-9B show the container 100 in different configurations of the hollow member 120 and the cup member 140. Some elements of the container 100 including the main body 110 are not shown in FIGS. 7A-9B for illustrative purposes. Further, some of the plurality of articles 10 are shown by dashed lines in FIGS. 7A, 7B, and 8A-9B. The plurality of articles 10 are not shown in FIG. 7C.

Specifically, FIGS. 7A, 7B, and 7C respectively show a top view, a top perspective view, and a front perspective view of the container 100 in a closed configuration 190 of the hollow member 120 and the cup member 140. Further, FIGS. 8A and 8B respectively show a top view and a top perspective view of the container 100 in an intermediate configuration 191 of the hollow member 120 and the cup member 140. Moreover, FIGS. 9A and 9B respectively show a top view and a top perspective view of the container 100 in an open configuration 192 of the hollow member 120 and the cup member 140. The grooved track 145 of the cup member 140 and the protrusion 162 of the cam arm 160 are shown by dashed lines in FIGS. 7A, 8A, and 9A for illustrative purposes.

For descriptive purposes, the cup member 140 may be rotated relative to the hollow member 120 in FIGS. 7A-9B. Accordingly, rotational directions described hereinafter correspond to rotation of the cup member 140 relative to the hollow member 120. Alternatively, the hollow member 120 may be rotated relative to the cup member 140. The hollow member 120 may be rotated relative to the cup member 140 by rotating the main body 110 (shown in FIG. 1 ) relative to the cup member 140. The cup member 140 and the hollow member 120 may also be rotated opposite to each other. It may be noted that the relative rotation between the hollow member 120 and the cup member 140 that achieves the open configuration 192 is opposite to the relative rotation between the hollow member 120 and the cup member 140 that achieves the closed configuration 190.

The hollow member 120 and the cup member 140 are rotatable relative to each other between the open configuration 192 (shown in FIGS. 9A and 9B) and the closed configuration 190 (shown in FIGS. 7A to 7C). Accordingly, the cam arm 160 moves between an engaged position 195 (shown in FIG. 7A) corresponding to the closed configuration 190 and a dispensing position 197 (shown in FIGS. 9A and 9B) corresponding to the open configuration 192 due to the relative rotation between the hollow member 120 and the cup member 140.

Referring to FIGS. 7A to 7C, in the closed configuration 190, the first and second openings 121, 141 are misaligned from each other (shown in FIG. 7C) to close the dispensing opening 106 (shown in FIG. 1 ). Further, in the closed configuration 190, the cam arm 160 may be in the engaged position 195.

Specifically, in the closed configuration 190, the first and second openings 121, 141 may be completely misaligned from each other with zero degree of overlap. For example, in the closed configuration 190, the first and second openings 121, 141 may be angularly offset from each other by about 180 degrees relative to the longitudinal axis 111 (shown in FIG. 1 ).

As shown in FIG. 7B, in the engaged position 195, the cam arm 160 may be configured to engage the bottom article 10A from the plurality of articles 10. Further, in the engaged position 195, the curved portion 168 may engage the inner surface 129 of the hollow member 120.

Moreover, in the engaged position 195, the protrusion 162 of the cam arm 160 may engage with the first groove end 145A (shown in FIG. 7A) of the grooved track 145. The bottom article 10A is received on the receiving portion 163 of the cam arm 160.

The cup member 140 may be rotated relative to the hollow member 120 in a first direction D1 (also shown in FIG. 1 ) about the longitudinal axis 111. Upon rotation of the cup member 140 relative to the hollow member 120 in the first direction D1, the hollow member 120 and the cup member 140 may achieve the intermediate configuration 191 (shown in FIGS. 8A and 8B).

Referring to FIGS. 8A and 8B, in the intermediate configuration 191, the first and second openings 121, 141 are at least partially aligned. As shown in FIGS. 8A and 8B, in some cases, the curved portion 168 of the cam arm 160 may engage the inner surface 129 of the hollow member 120 in the intermediate configuration 191. In some other cases, the curved portion 168 of the cam arm 160 may not engage the inner surface 129 of the hollow member 120 in the intermediate configuration 191. In the intermediate configuration 191, the protrusion 162 of the cam arm 160 may engage the grooved track 145 between the first groove end 145A and the second groove end 145B of the grooved track 145.

The cup member 140 may be rotated relative to the hollow member 120 in a second direction D2 (also shown in FIG. 1 ) opposite to the first direction D1 from the intermediate configuration 191, such that the hollow member 120 and the cup member 140 achieve the closed configuration 190 as shown in FIGS. 7A-7C and described above.

The cup member 140 may be further rotated relative to the hollow member 120 in the first direction D1 from the intermediate configuration 191. Upon further rotation of the cup member 140 relative to the hollow member 120 in the first direction D1, the hollow member 120 and the cup member 140 may achieve the open configuration 192 (shown in FIGS. 9A and 9B).

Though the bottom article 10A and the article 10 on top of the bottom article 10A are shown substantially aligned in FIGS. 8A and 8B, the bottom article 10A may extend outwardly relative to the article 10 on top based on the intermediate configuration 191.

Referring to FIGS. 9A and 9B, in the open configuration 192, the first and second openings 121, 141 are at least partially aligned with each other to define the dispensing opening 106. In the open configuration 192, a degree of alignment between the first and second openings 121, 141 may be at least 70%, at least 80%, at least 90%, or at least 95%. In some cases, the first and second openings 121, 141 may be fully aligned (i.e., 100% alignment) with each other in the open configuration 192. Further, in the open configuration 192, the cam arm 160 may be in the dispensing position 197.

The cam arm 160 may be further configured to move the bottom article 10A due to the relative rotation between the hollow member 120 and the cup member 140, such that, in the dispensing position 197 of the cam arm 160, the bottom article 10A at least partially extends through the dispensing opening 106 and may be removable from the container 100. That is, the cam arm 160 moves the bottom article 10 at least partially through the dispensing opening 106, such that the bottom article 10 can be removed from the container 100. Specifically, in the dispensing position 197 of the cam arm 160, the bottom article 10A may at least partially extend through the dispensing opening 106 to facilitate manual removal of the bottom article 10A from the container 100.

Therefore, due to the movement of the cam arm 160 from the engaged position 195 to the dispensing position 197, the bottom article 10A may extend outwardly relative to the article 10 on top in the dispensing position 197 of the cam arm 160. The engaging portion 164 of the cam arm 160 may engage the bottom article 10A and push the bottom article 10A towards the dispensing opening 106 during the movement of the cam arm 160 from the engaged position 195 to the dispensing position 197. Further, in the dispensing position 197, the protrusion 162 of the cam arm 160 may engage with the second groove end 145B of the grooved track 145.

A relative rotation between the hollow member 120 and the cup member 140 from the closed configuration 190 to the open configuration 193 in the first direction D1 about the longitudinal axis 111 may cause the cam arm 160 to move from the engaged position 195 to the dispensing position 197. After removal of the bottom article 10A from the container 100, a relative rotation between the hollow member 120 and the cup member 140 from the open configuration 192 to the closed configuration 190 in the second direction D2 opposite to the first direction D1 may cause the cam arm 160 to move from the dispensing position 197 to the engaged position 195 and engage a successive bottom article 10 (i.e., the article 10 that is on top of the bottom article 10A) from the plurality of articles 10. The successive bottom article 10 may therefore become the bottom article 10A after removal of the bottom article 10A from the container 100. The successive bottom article 10 may be received on the receiving portion 163 of the cam arm 160 and may be engaged with the engaging portion 164 of the cam arm 160. In this manner, the container 100 may allow sequential dispensing of successive bottom articles 10A from the stack of the plurality of articles 10. Thus, the container 100 may provide an easy to use dispensing mechanism to dispense the bottom article 10A from the container 100.

FIGS. 10A and 10B respectively show a front perspective view and a bottom perspective view of a container 200 for the plurality of arranged articles 10 (shown in FIGS. 12A and 12B) according to a second aspect the invention. Further, FIG. 11 shows an exploded perspective view of the container 200.

Referring to FIGS. 10A, 10B, and 11 , the container 200 comprises a main body 210 having a hollow tubular shape. The hollow tubular shape may allow the main body 210 to accommodate at least some of the plurality of articles 10 (shown in FIGS. 12A and 12B) therein.

The main body 210 comprises a first open end 212 and a second open end 214 opposing the first open end 212. In other words, the second open end 214 may be opposite to the first open end 212. The main body 210 extends along a longitudinal axis 211. Specifically, the main body 210 may extend along the longitudinal axis 211 between the first open end 212 and the second open end 214.

The container 200 further comprises a top member 220. The top member 220 may be at least partially received in the main body 210. In other words, at least a portion of the top member 220 may be received within the main body 210. The top member 220 may be fixedly coupled to the main body 210 at the first open end 212. Further, the top member 220 defines a top opening 221 therethrough in communication with the first open end 212.

The top opening 221 is configured to be selectively open or closed. For example, the container 200 may further comprise a cap 230 to selectively open or close the top opening 221. As shown in FIG. 10A, the cap 230 may be detached or removed from the main body 210 to selectively open the first open end 212 and the top opening 221 of the top member 220. Further, as shown in FIG. 10B, the cap 230 may be removably coupled to the main body 210 and configured to selectively close the first open end 212 and the top opening 221 of the top member 220. The cap 230 may define a closed top end 202 of the container 200.

The top member 220 may comprise a portion 222, which can be an annular portion, fixedly coupled to the first open end 212 of the main body 210. The portion 222 may define the top opening 221 aligned with the first open end 212. The top member 220 may further comprise an engaging portion 224 coupled to the portion 222. In some examples, the engaging portion 224 may be integral with the portion 222. The engaging portion 224 may extend at least partially into the top opening 221. Specifically, the engaging portion 224 may extend from an inner surface 223 of the portion 222 and extend at least partially into the top opening 221.

The engaging portion 224 may comprise an inclined planar surface 225 inclined obliquely to the longitudinal axis 211. The inclined planar surface 225 may be configured to engage with the top article 10B (shown in FIGS. 12A and 12B) and separate the top article 10B from a rest of the plurality of articles 10. The inclined planar surface 225 may subtend an angle α (shown in FIGS. 12A and 12B) relative to the longitudinal axis 211. In some examples, the angle α may be from about 10 degrees to about 60 degrees.

The container 200 further comprises a pusher 240 slidably received within the main body 210. The pusher 240 may slidably engage an internal surface of the main body 210. The pusher 240 may be movable along the longitudinal axis 211. The pusher 240 defines a movable closed bottom end 204 (shown in FIG. 10B) of the container 200. The main body 210 may comprise any suitable feature to retain the pusher 240 therein. For example, the main body 210 may comprise one or more stopping features 216 (shown in FIGS. 12A and 12B) extending into the main body 210 and proximal to the second open end 214. The one or more stopping features 216 may comprise a continuous wall, for example an annular wall, extending into the main body 210. The pusher 240 may engage the one or more stopping features 216, such that the pusher 240 may be retained within the main body 210.

The main body 210 may be configured to provide compression resistance and moisture barrier to the container 200. In other words, the main body 210 may protect the plurality of articles 10 (shown in FIGS. 12A and 12B) from compression (e.g., by external forces incurred by the container 200 during shipping or usage thereof), and may reduce or prevent contact between the plurality of articles 10 stored within the container 200 and moisture present in an external environment (e.g., a shower) where the container 200 is disposed. Therefore, the container 200 may reduce or prevent external moisture from being absorbed by the plurality of articles 10 stored within the container 200.

The main body 210 may be primarily made of a paper material and may be substantially free of plastic. Specifically, the main body 210 may comprise from 0% to 5% by weight of plastic. The main body 210 made of the paper material may comprise barrier materials to protect the main body 210, for example, against moisture, grease/oils, oxygen, etc. Further, the cap 230 may be made of a formed pulp with the barrier materials applied to the formed pulp. Moreover, the top member 220 may be made of a plastic. Alternatively, the top member 220 may be made of injection molded pulp, or a combination of injection molded paper and plastic. Similarly, the pusher 240 may be made of a plastic, injection molded pulp, or a combination of injection molded paper and plastic. Further, the container 200 may be substantially made of paper and/or aluminum. In some examples, the container 200 may comprise less plastic per dose than current liquid shampoo bottles. In some examples, the container 200 can contain less than 60% plastic, less than 55% plastic, or less than 50% plastic.

FIGS. 12A and 12B show cross-sectional views of the container 200 taken along a line 3-3 of FIG. 10A. The cap 230 (shown in FIG. 11 ) may be removed from the main body 210 and is not shown FIGS. 12A and 12B. The pusher 240 is in a first position 242 in FIG. 12A, and the pusher 240 is in a second position 244 in FIG. 12B.

As shown in FIG. 12A, the plurality of articles 10 may be received within the main body 210 and adjacent to the pusher 240. In this example the plurality of articles 10 are stacked on top of the pusher 240. In the first position 242 of the pusher 240, the plurality of articles 10 may be disposed between the top opening 221 of the top member 220 and the pusher 240 along the longitudinal axis 211. Further, the plurality of articles 10 comprises the top article 10B. As discussed above, the pusher 240 is in the first position 242 in FIG. 12A. The first position 242 may correspond to a storage configuration of the container 200. In the storage configuration of the container 200, the pusher 240 may rest proximal to the second open end 214 of the main body 210. For example, the pusher 240 may engage with and rest on the one or more stopping features 216 of the main body 210 in the first position 242.

The pusher 240 may be moved to the second position 244 (shown in FIG. 12B) upon application of a force on the movable closed bottom end 204 of the container 200 defined by the pusher 240 in a direction D3. The direction D3 may be from the second open end 214 towards the first open end 212 of the main body 210 and the top opening 221 of the top member 220 along the longitudinal axis 211. In some examples, the pusher 240 may be biased towards the first position 242 of the pusher 240. A biasing member, such as a spring, may bias the pusher 240 towards the first position 242.

As shown in FIG. 12B, upon application of the force on the pusher 240 in the direction D3, the pusher 240 may move to the second position 244. The second position 244 may be a position in which at least one of the plurality of articles 10 (e.g., the top article 10B) may be removable from the top opening 221. Specifically, the pusher 240 may be movable along the longitudinal axis 211 towards the top opening 221, such that the top article 10B from the plurality of articles 10 may be removable from the top opening 221. The top article 10B may engage with the inclined planar surface 225 of the engaging portion 224 when the pusher 240 may be in the second position 244. The inclined planar surface 225 may engage with the top article 10B and separate the top article 10B from the rest of the plurality of articles 10. The top article 10B may incline outwardly from the top opening 221 upon engagement with the inclined planar surface 225, and may be removed from the container 200. A successive article 10 from the stack may be similarly removed. In this manner, the container 200 may allow sequential dispensing of successive top articles 10B from the stack of the plurality of articles 10. Thus, the container 200 may provide an easy to use dispensing mechanism to dispense the top article 10B from the container 200.

FIGS. 13A, 13B, and 13C respectively show a front perspective view, a bottom perspective view, and another front perspective view of a container 300 for the plurality of arranged articles 10 (shown in FIGS. 16A and 16B) according to a third aspect of the invention. Further, FIG. 14 shows an exploded perspective view of the container 300.

Referring to FIGS. 13A to 13C and 14 , the container 300 comprises a main body 310 having a hollow tubular shape. The hollow tubular shape may allow the main body 310 to accommodate at least some of the plurality of articles 10 (shown in FIGS. 16A and 16B) therein.

The main body 310 comprises a first open end 312 and a second open end 314 opposing the first open end 312. In other words, the second open end 314 may be opposite to the first open end 312. The main body 310 extends along a longitudinal axis 311. Specifically, the main body 310 may extend along the longitudinal axis 311 between the first open end 312 and the second open end 314.

The container 300 further comprises a top member 320 (shown more clearly in FIG. 14 ). The top member 320 may be at least partially received in the main body 310. In other words, at least a portion of the top member 320 may be received within the main body 310. The top member 320 may be fixedly coupled to the main body 310 at the first open end 312. Further, the top member 320 defines a top opening 321 therethrough in communication with the first open end 312.

The container 300 may further comprise a movable member 330 rotatably coupled to the top member 320, such that the movable member 330 may be rotatable relative to the top member 320 about the longitudinal axis 311. The movable member 330 may define a closed top end 302 of the container 300.

The movable member 330 may further define a movable opening 331 therethrough. The movable opening 331 may be selectively aligned or misaligned with the top opening 321. The movable member 330 may be rotated along a direction D4 about the longitudinal axis 311 to align or misalign the movable opening 331 with the top opening 321 (e.g., misalign the movable and top openings 331, 321). The movable member 330 may also be rotated opposite to the direction D4 about the longitudinal axis 311 to align or mis align the movable opening 331 with the top opening 321 (e.g., align the movable and top openings 331, 321).

As shown in FIGS. 13A and 13B, the movable opening 331 of the movable member 330 may be aligned with the top opening 321 of the top member 320. The movable opening 331 may be selectively and at least partially aligned with the top opening 321 of the top member 320 to allow removal of the top article 10B (shown in FIGS. 16A and 16B) from the container 300. Further, as shown in FIG. 13C, the movable member 330 may close the top opening 321 (shown by dashed lines in FIG. 13C) when the movable opening 331 may be misaligned from the top opening 321.

The container 300 further comprises a pusher 340 slidably received within the main body 310 and movable along the longitudinal axis 311. The pusher 340 may slidably engage an internal surface of the main body 310. The pusher 340 defines a movable closed bottom end 304 (shown in FIG. 13B) of the container 300. The main body 310 may comprise any suitable features to retain the pusher 340 therein. For example, the main body 310 may comprise one or more stopping features 316 (shown in FIGS. 16A and 16B) extending into the main body 310 and proximal to the second open end 314. The one or more stopping features 316 may comprise a continuous wall extending into the main body 310. The pusher 340 may engage the one or more stopping features 316, such that the pusher 340 may be retained within the main body 310.

The main body 310 may be configured to provide compression resistance and moisture barrier to the container 300. In other words, the main body 310 may protect the plurality of articles 10 (shown in FIGS. 16A and 16B) from compression (e.g., by external forces incurred by the container 300 during shipping or usage thereof), and may reduce or prevent contact between the plurality of articles 10 stored in the container 300 and moisture present in an external environment (e.g., a shower) where the container 300 is disposed. Therefore, the container 300 may reduce or prevent external moisture from being absorbed by the plurality of articles 10 stored within the container 300.

The main body 310 may be primarily made of a paper material and may be substantially free of plastic. Specifically, the main body 310 may comprise from 0% to 5% by weight of plastic. The main body 310 made of the paper material may comprise barrier materials to protect the main body 310, for example, against moisture, grease/oils, oxygen, etc. Further, the movable member 330 may be made of a formed pulp with the barrier materials applied to the formed pulp. Moreover, the top member 320 may be made of a plastic. Alternatively, the top member 320 may be made of injection molded pulp, or a combination of injection molded paper and plastic. Similarly, the pusher 340 may be made of a plastic, injection molded pulp, or a combination of injection molded paper and plastic. Further, the container 300 may be substantially made of paper and/or aluminum. In some examples, the container 300 may comprise less plastic per dose than current liquid shampoo bottles. In some examples, the container 300 can contain less than 60% plastic, less than 55% plastic, or less than 50% plastic.

FIG. 15A shows a front view of a portion of the container 300. Some elements of the container 300 are not shown in FIG. 15A for illustrative purposes. FIG. 15B shows a cross-sectional view of the container 300 taken along a line 5-5 of FIG. 15A.

Referring to FIGS. 15A and 15B, the top opening 321 may comprise two symmetric portions 351A, 351B about a central axis 350. Each symmetric portion 351A, 351B may extend from the central axis 350 to a concave end 352. Each symmetric portion 351A, 351B may have a minimum width W1 at the central axis 350, and a maximum width W2 defined by the concave end 352. In some examples, the maximum width W2 may be greater than two times of the minimum width W1.

Similarly, the movable opening 331 may comprise two symmetric portions 354A, 354B about a central axis 353. Each symmetric portion 354A, 354B may extend from the central axis 353 to a concave end 355. Each symmetric portion 354A, 354B may have a minimum width W3 at the central axis 353, and a maximum width W4 defined by the concave end 355. In some examples, the maximum width W4 may be greater than two times of the minimum width W3.

Therefore, each of the top opening 321 and the movable opening 331 may comprise respective two symmetric portions (i.e., the symmetric portions 351A, 351B for the top opening 321 and the symmetric portions 354A, 354B for the movable opening 331) about the respective central axis 350, 353. Further, each of the top opening 321 and the movable opening 331 may extend angularly relative to the longitudinal axis 311. In some examples, each of the top opening 321 and the movable opening 331 may subtend a total angle β of at least 150 degrees about the longitudinal axis 311. In some examples, the total angle β may be from about 150 degrees to about 180 degrees.

The top opening 321 and the movable opening 331 are shown aligned with each other in FIGS. 15A and 15B, and therefore the corresponding central axes 350, 353 are also aligned with each other. Further, the top and movable openings 321, 331 may have substantially similar shapes. In some examples, the minimum width W1 of the top opening 321 may be equal to the minimum width W3 of the movable opening 331. Further, in some examples, the maximum width W2 of the top opening 321 may be equal to the maximum width W4 of the movable opening 331.

FIGS. 16A and 16B show cross-sectional views of the container 300 taken along line 4-4 of FIG. 13A. The top opening 321 and the movable opening 331 are aligned in FIGS. 16A and 16B. The pusher 340 is in a first position 342 in FIG. 16A, and the pusher 340 is in a second position 344 in FIG. 16B.

As shown in FIG. 16A, the plurality of articles 10 may be received within the main body 310 and stacked on top of the pusher 340. The plurality of articles 10 may be disposed between the movable member 330 and the pusher 340 along the longitudinal axis 311. Further, the plurality of articles 10 comprises the top article 10B.

As discussed above, the pusher 340 is in the first position 342 in FIG. 16A. The first position 342 may correspond to a storage configuration of the container 300. In the storage configuration of the container 300, the pusher 340 may rest proximal to the second open end 314 of the main body 310. For example, the pusher 340 may engage with and rest on the one or more stopping features 316 of the main body 310 in the first position 342.

The pusher 340 may be moved to the second position 344 (shown in FIG. 16B) upon application of a force on the movable closed bottom end 304 of the container 300 defined by the pusher 340 in a direction D5. The direction D5 may be from the second open end 314 towards the first open end 312 of the main body 310 along the longitudinal axis 311. In some examples, the pusher 340 may be biased towards the first position 342 of the pusher 340. A biasing member, such as a spring, may bias the pusher 340 towards the first position 342.

As shown in FIG. 16B, upon application of the force on the pusher 340 in the direction D5, the pusher 340 may move to the second position 344. The second position 344 may be a position in which at least one of the plurality of articles 10 may be removable from the top opening 321. Specifically, the pusher 340 may be movable along the longitudinal axis 311 towards the top opening 321, such that the top article 10B from the plurality of articles 10 may be removable from the top opening 321. Further, the top article 10B from the plurality of articles 10 may be removable from the movable opening 331 aligned with the top opening 321.

The top article 10B may be manually removed by moving the pusher 340 to the second position 344, and subsequently removing the top article 10B through each of the top opening 321 and the movable opening 331. The respective concave ends 352, 355 and the respective maximum widths W2, W4 (shown in FIG. 15A) of the top and movable openings 321, 331 may facilitate in gripping the top article 10B to manually remove the top article 10B through each of the top opening 321 and the movable opening 331. A successive article 10 from the stack may be similarly removed. In this manner, the container 300 may allow sequential dispensing of successive top articles 10B from the stack of the articles 10. Thus, the container 300 may provide an easy to use dispensing mechanism to dispense the top article 10B from the container 300.

FIGS. 17A and 17B are front perspective views showing different configurations of a container 400 for the plurality of articles 10 (shown in FIG. 20 ) stacked on top of each other according to a fourth aspect of the invention. Further, FIG. 18 shows an exploded perspective view of the container 400.

Referring to FIGS. 17A, 17B, and 18 , the container 400 comprises a main body 410 having a hollow tubular shape. The hollow tubular shape may allow the main body 410 to accommodate at least some of the plurality of articles 10 (shown in FIG. 20 ) therein.

The main body 410 comprises a first closed end 412 and a second open end 414 opposing the first closed end 412. In other words, the second open end 414 may be opposite to the first closed end 412. The main body 410 extends along a longitudinal axis 411. Specifically, the main body 410 may extend along the longitudinal axis 411 between the first closed end 412 and the second open end 414. The first closed end 412 may define a closed top end 402 of the container 400.

The container 400 further comprises a bottom member 420 (shown more clearly in FIG. 18 ). The bottom member 420 may be at least partially received in the main body 410. In other words, at least a portion of the bottom member 420 may be received within the main body 410. The bottom member 420 may be fixedly coupled to the main body 410 at the second open end 414. Further, the bottom member 420 may define a bottom opening 421 therethrough in communication with the second open end 414. The bottom opening 421 may extend angularly relative to the longitudinal axis 411.

The container 400 further comprises a movable member 430 movably coupled to the bottom member 420, such that the movable member 430 may be movable relative to the bottom member 420 between a closed position 432 (shown in FIG. 17B) and an open position 434 (shown in FIG. 17A). The movable member 430 defines a closed bottom end 404 of the container 400.

The movable member 430 may be rotated along a direction D6 about the longitudinal axis 411 to move the movable member 430 between the closed position 432 and the open position 434 (e.g., from the open position 434 to the closed position 432). The movable member 430 may also be rotated opposite to the direction D6 about the longitudinal axis 411 to move the movable member 430 between the closed position 432 and the open position 434 (e.g., from the closed position 432 to the open position 434).

In the closed position 432, the movable opening 431 may be closed. Specifically, in the closed position 432, the movable opening 431 may be misaligned from the bottom opening 421. In the open position 434, the movable opening 431 may be at least partially exposed to allow removal of the bottom article 10A (shown in FIG. 20 ) from the plurality of articles 10 from the container 400. Specifically, in the open position 434, the movable opening 431 may be at least partially aligned with the bottom opening 421.

The main body 410 may be configured to provide compression resistance and moisture barrier to the container 400. In other words, the main body 410 may protect the plurality of articles 10 (shown in FIG. 20 ) from compression (e.g., by external forces incurred by the container 400 during shipping or usage thereof), and may reduce or prevent contact between the plurality of articles 10 and moisture present in an external environment (e.g., a shower) where the container 400 is disposed. Therefore, the container 400 may reduce or prevent external moisture from being absorbed by the plurality of articles 10 stored within the container 400.

The main body 410 may be primarily made of a paper material and may be substantially free of plastic. Specifically, the main body 410 may comprise from 0% to 5% by weight of plastic. The main body 410 made of the paper material may comprise barrier materials to protect the main body 410, for example, against moisture, grease/oils, oxygen, etc. Further, the movable member 430 may be made of a formed pulp with the barrier materials applied to the formed pulp. Moreover, the bottom member 420 may be made of a plastic. Alternatively, the bottom member 420 may be made of injection molded pulp, or a combination of injection molded paper and plastic. Further, the container 400 may be substantially made of paper and/or aluminum. In some examples, the container 400 may comprise less plastic per dose than current liquid shampoo bottles. In some examples, the container 400 can contain less than 60% plastic, less than 55% plastic, or less than 50% plastic.

FIG. 19A shows a front view of a portion of the container 400. Some elements of the container 400 are not shown in FIG. 19A for illustrative purposes. FIG. 19B shows a cross-sectional view of the container 400 taken along a line 7-7 of FIG. 19A.

Referring to FIGS. 19A and 19B, the bottom opening 421 may comprise two symmetric portions 451A, 451B about a central axis 450. Each symmetric portion 451A, 451B may extend from the central axis 450 to a concave end 452. In some examples, each symmetric portion 451A, 451B may have a minimum width W5 at the central axis 450 and a maximum width W6 defined by the concave end 452. In some examples, the maximum width W6 may be greater than two times of the minimum width W5. Further, the bottom opening 421 may subtend a total angle γ1 of at least 150 degrees about the longitudinal axis 411. In some examples, the total angle γ1 may be from about 150 degrees to about 180 degrees.

Moreover, the movable opening 431 may comprise two symmetric portions 451C, 451D about a central axis 460. As shown in FIG. 19A, the central axis 460 may coincide with the central axis 450 when the movable and bottom openings 431, 421 are aligned with each other. Each symmetric portion 451C, 451D may extend from the central axis 460 to a concave end 454. Further, each symmetric portion 451C, 451D may have a minimum width W7 at the central axis and a maximum width W8 defined by the concave end 454. In some examples, the maximum width W8 may be greater than two times of the minimum width W7. Further, the movable opening 431 may subtend a total angle γ2 of at least 150 degrees about the longitudinal axis 411. In some examples, the total angle γ2 may be from about 150 degrees to about 180 degrees. In some cases, the movable opening 431 may have a substantially similar shape as the bottom opening 421.

FIG. 20 shows a cross-sectional view of the container 400 taken along a line 6-6 of FIG. 17A. The movable member 430 is in the open position 434 in FIG. 20 , such that the bottom opening 421 may be at least partially exposed to allow removal of the bottom article 10A from the plurality of articles 10 from the container 400. The bottom article 10A may be manually removed, for example, by grabbing the bottom article 10A through the bottom opening 421 and the movable opening 431. The concave ends 452, 453 and the maximum widths W4, W6 (shown in FIG. 19A) may facilitate in gripping the bottom article 10A to manually remove the bottom article 10A through each of the bottom opening 421 and the movable opening 431. Alternatively, the bottom article 10A may be manually removed by shaking or tilting the container 400, such that at least the bottom article 10A moves through the bottom opening 421 and the movable opening 431 under the force of gravity. Thus, the container 400 may provide an easy to use dispensing mechanism to dispense the bottom article 10A from the container 400.

FIGS. 21A and 21B are front perspective views of different configurations of a container 500 for the plurality of articles 10 (shown in FIGS. 22A and 22B) stacked on top of each other according to a fifth aspect of the invention. Further, FIG. 21C shows an exploded perspective view of the container 500.

Referring to FIGS. 21A to 21C, the container 500 comprises a main body 510 having a hollow tubular shape. The hollow tubular shape may allow the main body 510 to accommodate at least some of the plurality of articles 10 (shown in FIGS. 22A and 22B) therein.

The main body 510 comprises a first closed end 512 and a second open end 514 opposing the first closed end 512. In other words, the second open end 514 may be opposite to the first closed end 512. The main body 510 extends along a longitudinal axis 511. Specifically, the main body 510 may extend along the longitudinal axis 511 between the first closed end 512 and the second open end 514. The first closed end 512 may define a closed top end 502 of the container 500.

The container 500 further comprises a bottom member 520. The bottom member 520 may be at least partially received in the main body 510. In other words, at least a portion of the bottom member 520 may be received within the main body 510. The bottom member 520 may be fixedly coupled to the main body 510 at the second open end 514.

The successive bottom article 10 may be an article stacked on top of the bottom article 10A. As discussed above, the slider 640 may be biased away from the bottom opening 621. Therefore, in some examples, after removal of the bottom article 10A from the container 600, the slider 640 may automatically move away from the bottom opening 621. Further, the container 600 may allow sequential dispensing of successive bottom articles 10A from the stack of the plurality of articles 10. Thus, the container 600 may provide an easy to use dispensing mechanism to dispense the bottom article 10A from the container 600.

Referring to FIG. 29 , the container 700 can include post 710, which can be optionally included in any of the embodiments described herein. Post 710 can be position through at least one aperture in each dissolvable article to help keep the dissolvable articles inline throughout dispensing. Post 710 can puncture the dissolvable articles thereby creating an aperture and/or the aperture can be formed before the articles are packaged. Post 710 can have a smooth texture, to avoid or minimize tearing the dissolvable articles. Post 710 can be positioned in the interior of the container and can extend from top end 702, for example at approximately the center of top end 702, towards bottom end 704, along the length of the container. Post distal end 715 of post may not touch bottom end 704. Instead, a sufficient space may be required between post distal end 715 and the dissolvable article that is being dispensed, so one or more articles do not get stuck while dispensing. In addition, distal end 715 may not be too far from bottom end 704 because this could allow the article to twist or flip, making dispensing more difficult. Distal end can be positioned at a height that enables smooth dispensing, without the article that is being dispensed getting flipped, twisted, or otherwise impeded, even when only one article is left in the container. It was found that with fibrous articles, the post distal end can be spaced from the top surface of the next article to be dispensed (e.g., the article at the bottom end of the dispenser), and in some examples the post distal end can be spaced approximately 1.5 article heights away from the top surface of the next article to be dispensed.

FIGS. 30A and C-D show a perspective view of cup member 840, slider 850, and hollow member 820 in a closed, open/ready to dispense, and flexed/article being dispensed position, respectively. A container, like container 100 described herein, can further comprise a cup member 840 movably coupled to the hollow member 820 via one or more hinges 860, such that the movable member is movable relative to the bottom member between a closed position and an open position. The cup member can be movable along the longitudinal axis z and/or about the radial axis z. When in the open or flexed configuration, there is the space between cup member 840 and hollow member 820 defines opening 841, which the article can be dispensed through.

Slider 850 is shown in FIGS. 30B and 30E can be movably connected to cup member 840 and can be positioned opposite opening 841. Slider 850 can include engaging portion 853 configured to engage the bottom article from the plurality of articles. Engaging portion 853 can be positioned towards or at an end of slider 850 and can be positioned so engaging portion 853 extends into hollow member 820. Slider 850 can also include gripping portion 857 connected to slider at an end of slider 850 that is distal to engaging portion 853. Gripping portion 857 can be positioned approximately in line with the outer edge of movable member 840, alternatively gripping portion 857 can be positioned outside of the outer edge of movable member 840. On the same end but the opposite side of engaging portion 853, a spring can be connected to slider 850. In some examples the spring can be a flat spring. In some examples, the spring can be made from the same material as the slider 850 and/or the cup member 840. In other examples, the spring can be made from a different material, for example a metal, as the slider 850 and/or the cup member 840. In FIG. 30B, spring 855 of slider 850 is relaxed a, corresponding to the closed position in FIG. 30A and the open position in FIG. 30C. In FIG. 30E, spring 30E is flexed, corresponding to the flexed position in FIG. 30D.

To dispense articles, the dispenser is open and then slider 850 is moved in a defined path, generally towards opening 841, along a diameter d of cup member 840. Slide 850 can be moved by a user pushing gripping portion 857 with one or more fingers. As slider 850 is moved, engaging portion 853 moves in the radial direction towards opening 841. As engaging portion 853 moves, it carries an article towards opening 841 and presses spring 855 into a flexed position, as shown in FIG. 30E. In the flexed position, the spring presses against a ledge attached to the cup member, which flexes the spring. In the flexed position, shown in FIGS. 30D and E, the user can easily grab the article between two fingers and the spring gradually resets to the open position, shown in FIGS. 30B and C. The user can then close the dispenser by rotating cup member 840 about axis h defined by hinges 860, until it is coupled to hollow member 820.
